SEALING MEANS FOR VESSELS.

SPECIFICATION forming part of Letters Patent No. 686,624, dated. November 12, 1901. Application filed October 16, 1900- Sarial No. 83,224. (No model.)

To all whom it may concern:

Be it known that I, ABBOT AUGUSTUS Low, a citizen of the United States of America, residing at Brooklyn, county of Kings, State of New York, have invented new and useful Improvements in Sealing Means for Vessels, of which the following is a specification.

. My invention relates to means for hermetically sealing vessels; and to this end it consists in peculiarities in the shape of the vessel-neck and in the elements of the sealing device, all

u of which are fully set out in this specification and claimed at the end thereof.

In order that persons skilled in the art to which my invention appertains may understand, construct, and use my invention,I will proceed to describe it, referring to the accompanying drawings, in which-,

Figure 1 is a central vertical section of the vessel embodying my invention with the sealing and safety devices applied to it. Fig. 2 is a plan view of the same.

A is the body of the vessel.

B is the vessel-neck proper,provided on its exterior with screw-thread, as usual.

B is a flange turned inward a short distance from the top of said neck.

0 is a dome or chamber rising from the inner diameter of flange B.

D is a tubular discharge-opening or mouth rising from the crown of dome C.

E is a cork stopper located in the tubular mouth D.

H is a cap provided with screw-thread on the barrel of same to match with and take onto the thread upon the exterior of the vessel-neck B. The cap H is constructed to conform practically to the shapes of the vessel neck, dome, and mouth. It is closed at the top, and Within the upper part of the tubular portion a cup-shaped shell F is located, provided with packing material in its inner side or in the cup of the same. A packing material I is usuallylplaced upon the upper surface of the flange B, so that when the cap H is screwed down upon it a scaling is caused at this point. The main sealing is produced by the packing in shell F pressing upon stopper E and forcing it into the mouth of the vessel, which is tapered in the usual manner. Thus the vessel is closed at two points. In the barrel of the sealing-cap H holes or perforations J are made, through which wires or ribbons K are passed and attached and carried to the points upon the top surface of the vessel and secured by seals L, so that no tampering with the cap H can occur without destroying the seals L or by cutting thongs K.

Of course the vessel is opened by removing the cap H and then withdrawing the stopper E and closed again by replacing the same.

The function of the dome 0, located between the body of the vessel and its mouth,

be attached to a vessel which was provided with means for attaching the cap to it. My present invention consists in forming the neck of the vessel itself to perform the same function, thus cheapening the construction and obtaining equivalent results. Furthermore, it consists in the means for stoppering the vessel by a cork or stopper placed in the neck of the vessel and secured in place and prevented from loosening by means of the pressure of the top of the cap upon it. Thus the stopper is forced into the neck of the vessel to any degree, according to the necessities of the case.

Having now fully described my invention and the manner in which I have embodied it, what I claim as new and as my invention, and desire to secure by Letters Patent, is-

In a receptacle for liquids the combination consisting of the body of the vessel; tubular portion rising from said body and provided with means for securing a sealing-cap thereto; an annular flange turned inwardly at the top of said tubular-portion a dome-chamber rising from the inner edge of said flange; a tube rising from the crown of said domechamber; all constructed arranged and combined to form air-chamber between the body two subscribing witnesses, this 29th day of of the vessel and the discharging-tube,where-' September, 1900.

by air is admitted to the body of the vessel continuously While the contents are being ABBOF AUGUSTUS 5 discharged, substantially as specified. Witnesses:

In testimony whereof I have signed my WVM. W. BROSS,

name to this specification, in the presence of JAMES NV. EATON.
